The TYPO3 community has announced the release of a new Security Guide for system administrators, integrators and editors. According to the guide's creators, the new publication replaces the outdated "Security Cookbook" and covers various aspects of protecting installations of the open source TYPO3 content management system (CMS), as well as "general strategies and a peek into the workings of the Security Team".
